You may have an account which is classified as Administration however this doesn't mean you can do everything.

User Accounts will have some settings which basically tell Windows to jump in and stop things happening regardless of if you say it's OK to do so. If set too high it wont even ask you about them it will just outright deny you despite any account status.

There may be some policies installed within windows which prohibit you from installing or running certain file types or prohibit access to specific directories/folders in Windows (usually the Program Files and other users Documents). Check that there are not any (google it, I don't have time to explain this one since it is pretty involved).

Anti Virus, Internet Security and Anti Malware applications are known to block activities which they think could be the result of a virus or attack. Disabling it temporarily should stop this happening (however in some cases it cannot be 100% disabled - if your protection can't be disabled 100% temporarily I'd suggest getting a decent AV/IS/AMW software).

While it shouldn't be the case you may also want to check the properties of the Program Files and it's sub folders to see if they have been set to Read Only. If they have this may cause a problem however it's a long shot unless you've been playing around and not knowing what you are doing.

Do you have problems installing other software?

If you still can't figure it out and you trust me enough (look at my profile I have 130 questions answered and I'm sure the entire community would back me up) install Team Viewer and I will, when I get chance, take a look. I'm not sure when I will have time with Christmas coming but I'm sure we can arrange a time, just use this offer as a last resort and try everything else first.

eek I tried the Read Only trick and no help. I will get that Team Viewer and see if that can be of help. After the new year will be soon enuff. I still am waiting on my order of the robot to arrive. I have no problems installing other software and run several things as admin to get the best job done. Thanks for your help!

:) Got Team Viewer and it installed just fine.

Glad to hear you're back in business.

mad mad I meant Team Viewer installed do I can install something Still no luck w ez

If TeamViewer installed I can't see why ARC wont to be honest.

Have you tried uninstalling ARC (if it shows up in add/remove programs or whatever it's called these days) then deleting any trace of ARC from the Program Files folder and My Documents folders. Then try reinstalling?

I have uninstalled till I am exhausted. I will try deleting all the folders ty

Try this;

This is assuming your running windows 7:

Find the ARC Installer.msi file that you downloaded. Right click on the file and find the "Take Ownership" listing. Click on that and then try to run it again. You may even see "Run as Administrator". If so click on that.

If that doesn't work:

As a test, I would temporarily disable User Account Control and then see if you can install. If so, then we know that UAC is what is causing the problem with the installation.

1. Access User Control Panel from Start Menu -> Control Panel -> User Accounts and Family Safety -> User Account
2. Click on User Account Control settings link.
3. Move the Slider to Never Notify
4. Click OK to make the change effective
5. Reboot.

If that doesn't work you may have want to log into the built in Administrator account. I know you think you already are but these are two different things: The only difference between the 2 is that UAC will sometimes prompt your own admin account for permissions while it won't do that to the built-in admin account.

Assuming you are the admin, and you want to enable the built-in Admin Account : Start button > in the search box, type cmd > top left, right click at cmd.exe > click Run As Administrator > at the flashing prompt, compy/paste this command line ..... net user administrator /active:yes > press Enter key > exit cmd window. Your built-in admin account is now enabled > go to safe mode and you'll see it.

If that doesn't work do the following at your own Risk!:

1. Find the folder which your program wants to install/update itself into or you want to install/update the program into,
2. Right click that folder and press "Properties"
3. Click the "Security" tab.
4. Click "Advanced", the button at the very bottom of the window under the "Security" tab.
5. Click the "Owner" tab.
6. Click "edit" under the "change owner to" box.
7. Ironically, under the new "change owner to" box select the account that is not labeled "Administrator". It will probably just have your name on it. This is probably the non-administrative account you are using now. 7.5. Press Apply.
8. Accept any warning windows or anything that pops up by the way (I forgot if there were any).
9. Exit out of that window and go back to the "Permissions" tab.
10. Now click the "Change permissions" button at the bottom of that tab.
11. Select that same username/account name you selected earlier (not "Administrator"). There might be a big list and there might be more than one copy of that account. It doesn't matter which one you pick I think.
12. Press "Edit"
13. Fun part. Press "full control" under the list of permissions. Or select ones you want. I would just click "full control"
14. Press OK and you might be done! If you exit out back to the "Permissions" screen you will see that your account now has "full control.
15. You might not be done and be swarmed by a large number of windows saying that you can not change permissions for folders/files "xxxxx". Just click the red "x" and hope nothing bad happens. It may tell you that you might have caused system instability.
